Abstract

Regular exercise and high calcium intake possibly help to preserve bone mass. Little is known, however, about their role in preventing hip fracture. The physical activity and calcium intake of 300 elderly men and women with hip fractures were compared with those of 600 controls matched for age and sex. In both sexes increased daily activity, including standing, walking, climbing stairs, carrying, housework, and gardening protected against fracture. This was independent of other known risk factors, including body mass, cigarette smoking, and alcohol consumption. Strength of grip correlated with activity and was inversely related to the risk of fracture. Calcium intake was not related to the risk of fracture in women. Men with daily calcium intakes above 1g had lower risks. These findings point to the importance of elderly people in Britain maintaining physical activity in their day to day lives.

摘要

经常锻炼和摄入高钙可能有助于保持骨量。然而,关于它们在预防髋部骨折方面的作用,人们所知甚少。将300名髋部骨折的老年男性和女性的身体活动及钙摄入量与600名年龄和性别匹配的对照组进行了比较。在男性和女性中,日常活动增加,包括站立、行走、爬楼梯、搬运、家务和园艺,都能预防骨折。这与其他已知的风险因素无关,包括体重、吸烟和饮酒。握力与活动相关,且与骨折风险呈负相关。女性的钙摄入量与骨折风险无关。每日钙摄入量超过1克的男性骨折风险较低。这些发现表明,英国老年人在日常生活中保持身体活动非常重要。
